If you do find your notes, it would be interesting to know more. What you've said paints an interesting picture though and has already sparked a little more interest in it for me

I look forward to seeing the photos. Hints of the blue are still visible, I expect this time I will strip the paintwork back to bare metal as although it would be good to keep the 'history' of the car it also means any rust lying underneath will be missed and likely come through at some point.
I still have the green log book with presumably yourself and the owner before you listed, i'm wondering now if I may be able to find some details of his time with the car as presumably RAF Halton may have some information on him.
I think the car had around 3650 miles on the clock when I bought it although I have no idea if this is 103,650 or just a random number having been reset at some point, I guess i'll never know for sure! As for the gearbox, I believe you're right about it being the original as it has 1948 on the casing as apposed to the engine which has '46. The back axle has been leaking the whole time i've had it and I wouldn't be surprised if it's near empty. Do you remember thinking there was a large amount of play in the diff when you owned it? It seems to clunk a lot when turning the shaft back and forth (as does my '71 sprite which I think may have the same problem!). I'm guessing it is wear due to the oil leaking too much and just general wear? I've been buying up one of each oil seal whenever they become available and think I have all the ones for the diff now apart from the main one for the prop shaft (which I think is the bad one!) so hopefully will give it a full rebuild some day.
It's funny to hear the story of the person singing from the sunroof, i've joked occasionally with people that it would be good fun to hang out of while driving along as there's still no need for seatbelts... not sure if there is a law about sitting in your seat though.
Having heard the background behind the plastic padding I must admit, it probably did save it in the long term!
I had read somewhere that JB Weld was suitable for some engine related repairs so I just built up the landing by about 1mm between the two bores and sanded it level. Hopefully with it under compression with the new gasket on top it will hold it in place enough to stop it being blasted away. We will see!
Did the car ever have a bit of a bump at the rear do you know? The boot never fit right and from the picture I have of it in its original grey (probably sitting in your parents garden) it looks the same then. The chassis measured up straight enough though.
Glad to hear you got another TA14, it can't have been a bad car if you bought another. Would be great to see some pictures of that if you've put any up anywhere? I too have been sidetracked, shouldn't have bought a Sprite but I was itching to get into a classic and they are quite affordable, unfortunately it has needed a fair bit of mechanical attention which has delayed the Alvis.
